Installation

Require this package with composer:

composer req alexusmai/laravel-centrifugo

Open your config/app.php and add the following to the providers array:

'providers' => [
    // And uncomment BroadcastServiceProvider
    App\Providers\BroadcastServiceProvider::class,
],

Open your config/broadcasting.php and add new connection like this:

        'centrifugo' => [
            'driver' => 'centrifugo',
            'token_hmac_secret_key' => env('CENTRIFUGO_TOKEN_HMAC_SECRET_KEY',''),
            'api_key'               => env('CENTRIFUGO_API_KEY',''),
            'url'                   => env('CENTRIFUGO_URL', 'http://localhost:8000'), // centrifugo api url
            'verify'                => env('CENTRIFUGO_VERIFY', false), // Verify host ssl if centrifugo uses this
            'ssl_key'               => env('CENTRIFUGO_SSL_KEY', null), // Self-Signed SSl Key for Host (require verify=true)
            'use_namespace'         => env('CENTRIFUGO_USE_NAMESPACE', false),
            'default_namespace'     => env('CENTRIFUGO_DEFAULT_NAMESPACE', 'default:'),
            'private_namespace'     => env('CENTRIFUGO_PRIVATE_NAMESPACE', 'private:'),
            'presence_namespace'    => env('CENTRIFUGO_PRESENCE_NAMESPACE', 'presence:'),
        ],

Also you should add these two lines to your .env file:

CENTRIFUGO_TOKEN_HMAC_SECRET_KEY=token_hmac_secret_key-from-centrifugo-config
CENTRIFUGO_API_KEY=api_key-from-centrifugo-config
CENTRIFUGO_URL=http://localhost:8000

These lines are optional:

CENTRIFUGO_SSL_KEY=/etc/ssl/some.pem
CENTRIFUGO_VERIFY=false

Centrifugo namespaces

CENTRIFUGO_USE_NAMESPACE=true           // use centrifugo namespaces
CENTRIFUGO_DEFAULT_NAMESPACE=default:   // add to channel name default namespace - default:channel_name
CENTRIFUGO_PRIVATE_NAMESPACE=private:   // change default "private-" laravel prefix to private namespace - private-channel_name -> private:channel_name
CENTRIFUGO_PRESENCE_NAMESPACE=presence: // change default "presence-" laravel prefix to presence namespace - presence-channel_name -> presence:channel_name

Don't forget to change BROADCAST_DRIVER setting in .env file!

BROADCAST_DRIVER=centrifugo

Basic Usage

For broadcasting events, see official documentation of laravel

A simple client usage example:

<?php
declare(strict_types = 1);

namespace App\Http\Controllers;


use denis660\Centrifugo\Centrifugo;
use Illuminate\Support\Facades\Auth;

class ExampleController
{

    public function example(Centrifugo $centrifugo)
    {
        // Send message into channel
        $centrifugo->publish('news', ['message' => 'Hello world']);

        // Generate connection token
        $token = $centrifugo->generateConnectionToken((string)Auth::id(), 0, [
            'name' => Auth::user()->name,
        ]);

        // Generate private channel token
        $apiSign = $centrifugo->generatePrivateChannelToken((string)Auth::id(), 'channel', time() + 5 * 60, [
            'name' => Auth::user()->name,
        ]);

        //Get a list of currently active channels.
        $centrifugo->channels();

        //Get channel presence information (all clients currently subscribed on this channel).
        $centrifugo->presence('news');

    }
}
